DAG: Live Cell Diacylglycerol Assay

Bright Fluorescent Biosensors for Diacylglycerol

DAG Assay Performance

Off the shelf kits include the DAG sensor in BacMam – a BSL-1 viral vector for efficient delivery to most cell types. Purified BacMam, AAV, Lenti vectors are available by request.

    • Easily detectable response on plate readers or imaging systems
    • Consistent well-to-well expression
    • High signal-to-noise ratio

Multiplex Assays

Red DAG sensor multiplexed with a green cAMP sensor indicates dose-dependent signaling via a calcitonin receptor.

A Robust & Versatile DAG Assay Kit

  • Detect diacylglycerol signaling in real time
  • Screen Gq coupled GPCRs in living cells
  • Viral vector delivery to practically any cell type
  • Target to microdomains or specific cells in mixed cultures

Simple Protocol

    • Minimal liquid handling
    • No cell lysis
    • 96 or 384 well compatible

Which Sensor is Right for You: Up or Down?

Downward DAG starts out bright and decreases in fluorescence when diacylglycerol levels increase. This assay is easily detected on fluorescence plate readers and helps with imaging cells that have low expression efficiency.

Upward DAG starts out dim and increases in fluorescence when when diacylglycerol levels increase. This DAG assay is easily detected on fluorescence plate readers or imaging systems.


“We have been delighted to work with MontanaMolecular ever since we noticed a publication  5 years ago concerning DAG sensors that MM had created and that we employed subsequently to examine DAG signaling in cardiac cells. We were impressed first by the friendly and scientific way in which MM scientists interacted with us. Then, we were impressed how MM scientists helped us generously to reach our goals to monitor DAG changes and to consider new approaches to develop and exploit sensing molecules.   Recently, MM has helped us design and build BaculoViruses to express and manipulate important proteins in a variety of cells that interest us.  Again, we have been delighted by the competence of MM scientists, the reliability of the products we received, and the pleasure that MM scientists show in accomplishing great science in collaboration.  It our genuine pleasure to recommend MM to all our colleagues with similar scientific interests and needs.”
